To all w/wmt 'may concern.'

Be it known that l, l/Vnmmir lV. NUenN'r, a. citizen of the United States9 residing at Chicago, in the county oit Cook and State of Illinois, have invented certain 'new and useful Improvements in Uil-Sediment Removers, ot which the 'following` is a specification.

Mv invention relates to sediment removing' mechanism and has `tor one ot its objects the provision ot simple and etiicient means for removing sediment from oil, and the like.

A further object is the provision of a tank with aV sediment gatherer olfA materia adapted to receive sediments deposited by gravity or otherwise onto such gathering member.Y together with means for removing;

, this sediment ,trom the gathering` member.

Other objects will appear hereinafter.

Embodiments oi' my invention are shown in the accompanying drawing, forming` a part of this specification, and in which Fig. l is an end view of the device ein* bodying` my invention with portions broken away to show underlying` parts;

Fig. 2 is a side View oit the same showing` a portion broken away to show internal parts;

Fig. 3 is a view similar to Fig. l, except showing a modified form ot my invention; and

Fig. i is a view similar to Fig'. l, except showing a modified 'form oit my invention.

In Figs. l and 2 i have shown a settling; tank 5 Vshaped in cross-section. although it will be apparent that the settling tank may be formed in other desirable shapes. The V-form is convenient since it gives a considerable surface :tor depositing sediments from the oil and other substances. Near the bottom of tank 5 is an oil inlet 6 and near the top is an oil outlet 7.- Dirty oil in passage from opening' 6 to 7 in the tank tends to free the foreign materials which are heavier than the oil7 permitting such foreign materials to tall to the bottom. Disposed on the inclined walls 8 oi the tank 5 I provide a web 9 which may be of felt, fabrics7 or many other lexible substances. In the form shown in Figs. l and 2 l have indicated the end portions oi the web 9 extending over roilers l() at the top side edges ot tank 5 and wound on windlasses or roll-ers' 'il outside of tank 5. it will be apparent that by turning either windlass the web 9 will he moved toward Y such windlass so as to present new sur@ faces to the interior loi tank 5. Between each roller l0 and Windlass ll provide a plateA or blade 12 which is adapted to engage the web 9 with suihcient pressure to The sediment falls down T01 holdv the web 9 nearl the bottom of l l the tank l provide a roller 16 which .is

preferably journaled in the ends of thel tank 5 so that the web passes under such roller keeping the web in` close contact with the inclined sides 8 of the tank.

The rollers l0 and 11 are mounted in any desirable manner on the outside ot tank 5,a such as by extending the side walls 17 and Si)k journaling the rollers in such extensions.

These extension also tacle 13. f

in Fig. 3 i have shown a slightly, modified form of the inventionk in which the tank 5 is formed much deeper and narrow-er than the form shown in Fig.` l. This in-` creases the amount oi web 9vexposed ,to the oil in the tank and thereby increases 'the capacityv of the apparatus in' removing sediment from the oil. From 4thisv iti` will be apparent that theV shapes and sizes of the tanks 5 maybe varied greatly. in the form of l have indicated-'the web 9 as being attached as at 9 to one ofthe side walls 8 and passing` over aroller 10 at another top edge ot the tank. The web 9 then passes by a scraper 12'and is attached to a windlass 1l simi-lar to that already descrihed. `The tank 5 is also proivided with one receptacle 13 with its opening 11i above abucket l5 for catchingthe sediment removed .from the web 9. ln this form I have indicated the roller 16 as being' a free metal weight and 'restingon the web 9 so that when the web is wound up on windlass 1l theroller 16 is raisedftroin its iull position to the top ot' the tank, as indicated by the dotted lineposition,

In Fig. 4 l have shown .another orm of myy inventionin Which the tank is indicated help '.torm the recepas bei-ng rectangular in cross-section The tank isprovided with the intake 6 and discharge 7, as already described. On the rectangular bottom of the tank in this form I provide a frame 18 which may be a. piece of sheet metal With its edges 19 turned over Y a lat rectangular piece of fabric, felt, or other suitable sediment gathering material 20. The edges 19 hold the member 2O in position on frame 18; The member 20fmay be omitted?" and in such case the edges 19 would form the sides ofv a pan to retain material on saidvv frame 18. A cord or cable 2r is secured substantially centrally of thel frame 187 and passed over pulleys 22 and 23` at the top` of the tank and Wound on a` Windlass 24. In the operation of this form-ofthe device the element 18-19-20iis raised tothe top of the tank, such as indi'- cated in dotted* lines 215` in Fig; L1, Where the sediment may be scraped odv Withy a knife, hoe, or other suitable scraper, not shown; A receptacle 13 is preferably provided atene side oft the tank with a pail or bucket 15 under the opening 1st, as before described. In this connection it Will be apparent that When the Web 9 inY Fig. 3l is drawn tov its uppermost dotted line position 9' a knife or other implement, not shown, may be used for scraping 1na terials from the Web over the side of the tank into receptacle 13 just as is done in the device illustrated in Fig. il, ln fact to clean'- the partof the web in Fig. 3' between the pulley 10 and the point Qvrhere it is' seeured,'the use o-t some in'rplement for scraping-the sediment from the top overinto receptacle 13 is required. Also, inthe fornr shown in Fig. I a hoe-like implement, not shown, might' be used to scrape the Web on the inclined Walls, drawing the materia-ls up over the pulleys 10 for depositingin receptacles 1 As the oil passes* upwardly from openingK 6l to' the open-ing 7 the sediment settles by gravity on tothe iveb'or sediment gatliering member and toremove this sediment in: the device of. Fig; 1 one of the windlassesr 1.1' is: rotated whichY drawsthe web up over pulley 1() past scraper 12onto said Windlass. As the Web passes under the scraper 12` it scrapes oil' the sediment which slides over the scra )er into the receptacle 13.' ItV Willi be apparent that either of the. windlassesl 11'- may be operated? so that the. Web may be moved eitherto one side or the other` to positionY new portions of the web inthe tank 5;

In the device of Fig. 3 there is but one Windlass 11 and therefore the web can be Wound in but one direction, the Weight roller 16 serving to hold the web to position it in the bottom'. ofthe tank when un- Wound; It Will also be apparent that Without disturbing` the web at all` a. hoe-like or other implement, not shown, can be used to scrape the sediment up the sides of the tank over into receptacle 13.
